so today i instaled my ams single cat back and ams test pipe and the day was going great. Shortly afterwards the check engine light came on. why? i have no idea. it is still on. to make it wose it started snowwing ALOT and as i drifted into my neihborhood (thanks to my summer tires) a warning came up on my screen and my steering felt a little looser. the warning read 4wheel drive system service required. when i turned my car off an turned it back on the warning was gone but the car still felt weird. has this happen to anyone before? what can be wrong? how can it be fixed? PLEASE HELP!

 

Test pipe triggered an O2 sensor error. Use your handy dandy 50 dollar OBD-II reader to pull the code and verify. It's probably in your glove box of your 30k rice mobile, or perhaps in your garage. Or it might be in your second vehicle, or your work bench. Try your glove compartment first, that's where a lot of people keep theirs.

As for the other thing... umm... you done damaged something? How bad did you "drift into your neighborhood"? Like "I drifted into a curb like a silly goose running Advans in the snow"?
